IMPROVEMENT IN THE CONSTRUCTIO OF CANS.

Specification forming part of Letters Patent No. 50,022, dated September19, 1865.

To allwhom tt mat concem:

Be it known that I, HENRY W. MILLAR, of tica, in the county of Oneidaand State of New York, have invented a new and Improved Bottom for(Ja-ns, Pails, &c.; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure lis a longitudinal Vertical section of a can with its bottomconstructed according to my invention, taken in the line a; x, Fig. 2.Fig. 2 is a View of the bottom when looking into the can.

Similar letters of reference indicate like parts. y

My invention consists in constrncting a bottom for a can, pail, or othermetallic vessel in a conical form, or in theform of a frustum of a cone,its apex or point extending upward into the can, so as to strengthen theresisting-power of the bottom, and also, when it may be desirable, toafl'ord a better opportunity for drawing off the entire contents of thecan by t'aucet or the like.

To enable others to fully understand my invention, I will proceed todescribe it.

A represents the body of a milk-can constructed in the ordinary way, a abeing strips soldered around the same for the purpose of strengtheningit and protecting it against injury, as usual. i

To form the bottom, I take several triangular pieces of metal, B, andsolder or otherwise ``join their edges together, so that when they icalbottom B and body A-are then joined together by solderin g or in anysuitable manner. I then secure'to this the rim O, which is to form thepedestal of the can, its flange c extendin g up above the rim Z) andrestin g against the body Aof the can. Applying the pedestal inward thesidesof thecan and tends to loosen the joints where the said bottoms arefastened to the sides.

With a bottom made according to my invention this disadvantage isobviated, for the rea` son that a weight resting upon it causes it tooperate on the principle of the arch; but there is no liability ofstraining outward the sides of the can, for the reason that the bottomedges of said sides are confined by the rim O on the base of the saidconical bottom B. The parts thus secured are held firmly together andremain in perfect condition so long as the material of which they arecomposed lasts.

I purpose also making these bottoms in the form of. the frustum of acone, the points being bent inward and soldered together orotherwisesecured together, or actual] y cut off and a cap or plate placed overthe top or opening.

A can constructed in this way, with a conical bottom affords a betteropportunity for entirely drawing olf its contents when it is de! sirableto use a cock or faucet, which may be inserted at thelowest part, andthus completely drain the can, as can be readily understood, and this isa desirable feature in stationary g cans used for containing oil,molasses, 8m.

What I claitn as my invention,and desire to secure by Letters Patent,is-

Gonstructing the bottom and secnring the same tothe body of the can inthe manner shown and described.

The above specification of my invention signed by me this Slst day ofMarch, 1865.
